Civil Engineering Materials
The basic materials used in civil engineering applications or in construction are:wood,concrete,bitumen(沥青),structural clay and concrete units,reinforcing and structural steel.
These materials are sometimes called structural materials.Added to these materials are plastics,soils,and aluminum.All these materials are used in a number of civil engineering structures,such as dams,bridges,roads,foundations,liquid-retaining structures,waterfront structures,bulidings,and retaining walls.The most important highway materials are soils,aggregates,bituminous binder,lime,and cement.
Wood is derived from trees and can bu used directly as pieces of lumber obtained from the log(原木)or as a raw material in the manufacture of various wood products.Plywood,glulaminated timber,and oriented strandboard are some of the wood products used most commonly in construction.
Concrete is a basic construction material made with Portland cement as a primary ingredient.Portland cement (and other types of cement)are also used in the manufacture of many other construction materials.Concrete is used in combination wiht other distinctly different materials,such as steel reinforcing bar,polypropylene fibers,and high-strength wires to produce different types of concrete.
Bitumen ,which comes in variety of forms,is combined with other raw materials in the construction of pavements,roof shingles,waterproofing compounds,and many others,Structural clay and concrete units,commonly called bricks and blocks,are the principal elements in the construction of masonry walls.Structural steel is used in many forms and shapes for the construction of railroad ties,high-rise builidings,roof trusses,and many more.These basic materials are selected for their properties,performance,availability,aesthetics,and cost.Knowledge of all these aspects is essential in selecting a suitable material for a particular situation.
In addition to the basic materials described above,there are a significant number of secondary materials of construction.Sealants(密封剂),adhesives,floor and wall coverings,fasteners,and doors and windows come under this category.Most of these materials,also called nonstructural materials,are selected based on quality guidelines and aesthetic considerations.

土木工程材料
使用的基本材料在土木工程中应用或在施工 有:木材,混凝土,沥青(沥青),struct 乌拉尔 粘土和混凝土单元,巩固和结构钢.这些材料有时被称为结构材料.加上这些材料是塑料的,土壤和铝.所有这些材料是用一些土木结构,例如水坝,桥梁,道路,基金会 液体挡土结构,海旁建筑物,综合布线系统,及挡土墙.最重要的公路材料都是土,碎石,沥青粘合剂,石灰及水泥.木材是由树木和卜可直接用作件木材所得的日志(原木)或作为 原料制造各种木制品.胶合板,glulaminated木材,定向刨花板正部分的木材产品用目前最常用的建筑.具体是一个基本的施工材料与普通硅酸盐水泥为主要成分.硅酸盐水泥(和其他类型的水泥),也可用于制造许多其他建筑材料.具体是在合并使用其他不同的材料,如钢筋产品,聚丙烯纤维 高强钢丝制作不同的混凝土.沥青,它是形式多样,结合其他原料建造的人行道,油毡屋面防水化合物,和许多人一样,结构性粘土和混凝土单元,俗称砖头块等 为主要内容的建筑墙体.结构钢用在许多不同的形式,形状为修建铁路的关系,高层建筑中,屋架,更多.这些基本材料的选择是基于其性质,性能,可用性,美学及成本.知识,所有这些方面都必须选择一个适当的材料在特定情况.除了基本的材料所述,还有相当数量的辅助材料建造.sealants(密封剂),粘合剂,地板和墙壁饰物,紧固件,门窗也属于这一类.大部分材料,又称软性材料中,选定基于质量方针和美学的考虑.
